Hello,

all my pages in production went blank today for no apparent reason. Here is an example: [Home - Florida Atlantic University - Cannabis Studies - Florida Atlantic University](https://fau.cannabisstudiesonline.com/home-1)

I attempted to debug the issue by redeploying my code using `hs watch`, and received the following output:

 ![88989478-5bf9ab00-d2f9-11ea-9dff-6f53ef558457](https://d2qpr2jzcazej7.cloudfront.net/original/3X/1/2/12f45e73574e6eb796837284605c2e0b1ff2e561.png)  
After deleting the `left` and `right` properties in all my templates, I was able to restore the pages back to their original state. For example: [https://fau.cannabisstudiesonline.com](https://fau.cannabisstudiesonline.com)

 ![88990465-9fedaf80-d2fb-11ea-8a41-bdc795a16089](https://d2qpr2jzcazej7.cloudfront.net/original/3X/e/e/eeae36d101115f58e7dfcb8d5ed40705246fa063.jpeg)  
Can anyone tell me why the `left` and `right` fields are now unrecognized on the padding object? Also, why should their inclusion completely break the page layout? They are documented as valid right here: [Drag and Drop Areas HubL Tags - HubSpot docs](https://developers.hubspot.com/docs/cms/hubl/tags/dnd-areas#drag-and-drop-section-code-dnd-section-code-)

What is more, they were working just fine until about twelve hours ago, when everything suddenly broke. We have over six mission-critical domains based on the same template, generating thousands of dollars of revenue daily. All of them went down simultaneously. My suspicion is that some breaking changes were released on the backend without notice.

Closing, I got an answer from the dev team: [Error Validating Template: Unrecognized field "left" · Issue #268 · HubSpot/hubspot-cli · GitHub](https://github.com/HubSpot/hubspot-cms-tools/issues/268)
